Detailed Description
The MAX5460
–
MAX5468 consist of a fixed resistor and a
wiper contact with 32-tap points that are digitally con-
trolled through a 2-wire serial interface. Three resistance
values are available: 10k
(MAX5466/MAX5467/
MAX5468), 50k
(MAX5463/MAX5464/MAX5465), and
100k
(MAX5460/MAX5461/MAX5462).
The MAX5462/MAX5465/MAX5468 are designed to oper-
ate as potentiometers. In this configuration, the low termi-
nal of the resistor array is connected to ground (pin 2).
The MAX5461/MAX5464/MAX5467 perform as variable
resistors. In these devices, the wiper terminal and high
terminal of the resistor array are connected at pin 5.
The MAX5460/MAX5463/MAX5466 are similar variable
resistors, except the low terminal is connected to
ground (pin 2).
Digital Interface Operation
The MAX5460
–
MAX5468 have two modes of operation
when the serial interface is active: increment and
decrement mode. The serial interface is only active
when
CS
is low.
The
CS
and U/
D
inputs control the position of the wiper
along the resistor array. When
CS
transitions from high to
low, the part will go into increment mode if U/
D
is high,
and into decrement mode if U/
D
is low. Once the mode is
set, the device will remain in that mode until
CS
goes high
again. A low-to-high transition at the U/
D
pin will incre-
ment or decrement the wiper position depending on the
current mode (Figures 1 and 2).
When the
CS
input transitions to high (serial interface
inactive), the value of the counter is stored and the
wiper position is maintained.
Note that when the wiper reaches the maximum (or mini-
mum) tap position, the wiper will not wrap around to the
minimum (or maximum) position.
